it's a simple idea .
user sell something to me.
I send their coins from the hot wallet to his user wallet ( a wallet that I make on my website) , the trick is he can see the bitcoins on his wallet but somehow he can't withdraw them to external wallet, this is kind of automatic escrow , so if his sold goods are defective admin can cancel the transaction as long as it still under X time or X blockchain confirmations.
I know I can do this by just not sending the coins and just saying " X BTC on hold"
but I want user to verify that X ammount of BTC was Really sent To his wallet via blockchain .

I hope I made my idea clear .

also any idea how to moderate a website that send bitcoins in exchange of goods , I mean I need a database and an admin panel ( cancel transaction , user history ..etc)to do that as I'm not a tech savvy person .

also is it safe to hire a 3rd world developper for such financial project?

can you guys just clarify the path for a fellow Bitcoiner .thanks.

yes , you sound like you understand me correct.
